Gas stove deflecting air-wall structure

ABSTRACT

The invention discloses a gas stove deflecting air-wall structure including a jet airflow discharging device disposed near a gas stove consisted of a U-shaped tube from three individual tubes using universal joints. Within each of the tubes is provided with a squirrel cage, and adjacent tubes are connected by means of multi-directional swivels. One of the squirrel cages is connected with a motor that drives and rotates the squirrel cages, and the airflow generated within the tubes is discharged through outlets at the top thereof, thus forming a invisible and transparent air-wall. The air-wall formed then forwards smoke produced by a smoke exhaust upwards to the suction area of the smoke exhaust, thereby preventing the smoke dirtying kitchen utensils and harming the health as being inhaled by human lungs.

BACKGROUND OF THE INVENTION

[0001] (a) Field of the Invention

[0002] The invention relates to an invisible air-wall structure formedbetween a gas stove and a smoke exhaust by means of a jet airflowdischarging device. The air-wall then separates the air in and out ofthe air-wall and forwards the smoke produced by the smoke exhaustupwards to the suction area of the smoke exhaust, thereby preventing thesmoke from dirtying kitchen utensils and harming the health as beinginhaled by human lungs.

[0003] (b) Description of the Related Art

[0004] A conventional gas stove is generally provided with a smokeexhaust above that discharges the smoke produced by the gas stove. Adistance usually exists between the gas stove and the smoke exhaust, andthus forming dead corners unreachable by the smoke exhaust. Andtherefore part of the smoke produced yet dirties kitchen utensils oreven affects the health as being inhaled by human lungs.

SUMMARY OF THE INVENTION

[0005] Therefore, an object of the invention is to provide a jet airflowdischarging device for installing near a common gas stove. The jetairflow discharging device, through rotation of a three-segmentalsquirrel cage driven by a motor, is capable of separating the air in andout of an invisible air-wall formed upwards from the jet airflowproduced, thus forwarding the smoke upwards to the suction area of thesmoke exhaust. The suction deficiency of the smoke exhaust is thencompensated for preventing the smoke from dirtying kitchen utensils andharming the health as being inhaled by human lungs.

[0006] Another object of the invention is to drive the smoke produced bydirecting the airflow upwards to the suction area of the smoke exhaustby disposing a deflecting air-wall capable of compensating the airflowdeficiency at the two ends of the tube of the squirrel cage,respectively.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Illustrations of the invention shall be given with theaccompanying drawings hereunder.

[0013] Referring to FIG. 1, above a common kitchen gas stove 1 isprovided with a smoke exhaust 2, whose blow discharges the smokeproduced during cooking. The characteristics of the above shall bedescribed below.

[0014] As shown in FIG. 2, near the gas stove 1 is disposed with a jetairflow discharging device 3 consisted of three tubes 31, 32 and 33, twouniversal joints 34 and 35, and a motor 36. Wherein, two adjacent tubes31 and 32, 32 and 33, are connected to the universal joints 34 and 35 bymeans of screw bolts, respectively, to form a U-shaped tube. In thetubes 31, 32 and 33 are provided with squirrel cages 311, 321 and 331,respectively, as shown in FIG. 3. An axle of the motor 36 is connectedto the squirrel cage 311 within the side tube 31, and the squirrel cage311 within the side tube 31 is also connected to the squirrel cage 321within the middle tube 32 by means of a multi-directional swivel 341.The squirrel cage 321 within the middle tube 32 is further connected tothe squirrel cage 331 within the other side tube 33 by means of amulti-directional swivel 351. Thus the motor 36 is able to drive androtate the three squirrel cages 311, 321 and 331. In addition, The motor36 may also be used to drive the multi-directional swivels 341 and 351in the universal joints 34 and 35 for further driving and rotating thesquirrel cages 321 and 331. Also, the three squirrel cages 311, 321 and331 may be combined using segmental joining methods. Referring to FIG.3, the airflow produced during the rotation of the squirrel cages 311,321 and 331 within the tubes 31, 32 and 33 is discharged through outlets312, 322 and 332 at the top thereof.

[0015] Referring to FIGS. 4 and 5, reflecting blades 313, 323 and 333are disposed at the two ends of the tubes 31, 32 and 33 (as reflectingblades in vents of air conditioners) capable of compensating airflowdeficiency at corners by adjusting angles of the blades. Referring toFIG. 1, in the jet airflow discharging device 3 according to theinvention, the motor 36 drives the squirrel cages 311, 321 and 331 toproduce airflow that travels upwards through the outlets 312, 322 and332 and form an invisible (transparent) air-wall A. The air-wall Aseparates the air in and out of the air-wall A and forwards the smoke tothe suction area B of the smoke exhaust 2, thereby compensating thesuction deficiency of the smoke exhaust 2 and further preventing thesmoke from dirtying kitchen utensils and harming the health as beinginhaled by human lungs.

[0016] In addition, the jet airflow discharging device 3 according tothe invention may not only be disposed between the gas stove 1 and otherkitchen units but may also be combined with the gas stove 1 or otherkitchen units during the production process to become one body.

[0017] Conclusive from the above, a jet airflow discharging deviceaccording to the invention is disposed near a kitchen gas stove, suchthat an invisible air-wall is formed using jet airflow that forwardssmoke produced upwards to the suction area of a smoke exhaust, therebypreventing the smoke dirtying kitchen utensils or harming the health asbeing inhaled by human lungs. It is of course to be understood that theembodiment described herein is merely illustrative of the principles ofthe invention and that a wide variety of modifications thereto may beeffected by persons skilled in the art without departing from the spiritand scope of the invention as set forth in the following claims.
